Prefabricated sandwich thermal-insulation laminated wallboard and manufacturing method

Abstract

The invention relates to a prefabricated sandwich thermal-insulation laminated wallboard. The wallboard is characterized by comprising an inner prefabricated wallboard, an outer prefabricated wallboard, a thermal-insulation layer (2) located between the inner prefabricated wallboard and the outer prefabricated wallboard, and a thermal-insulation connecting piece, wherein the inner prefabricated wallboard and the outer prefabricated wallboard are poured with longitudinal and transverse tensioned bar plane frames as skeletons; the thermal-insulation connecting piece passes through the inner prefabricated wallboard, the outer prefabricated wallboard and the thermal-insulation layer (2) in an embedded way; and the thermal-insulation layer (2) is a foamed thermal-insulation material and is poured between the inner prefabricated wallboard and the outer prefabricated wallboard. According to the invention, the thermal-insulation material overcomes the shortcomings of great needs of labor and low automation degree of the traditional prefabricated sandwich thermal-insulation wallboards through one-shot injection in a factory and adequate filling and compacting of a cavity in virtue of physical and chemical changes of the material; meanwhile, the thermal-insulation material and the contact surface of the inner and outer prefabricated wallboards are effectively bonded together, so rain water is prevented from intruding through gaps produced by stripping of the inner and outer prefabricated wallboards and is thus prevented from influencing the thermal insulation effect of the thermal insulation layer.

Problems solved by technology

[0010] The technical problem to be solved in the present invention is that the prefabricated sandwich insulation wallboard in the prior art requires manual participation in the whole process of making the insulation board, and the production efficiency is low, and when the FRP insulation connector is fixed, the insulation board is easily damaged, and the production The yield rate is low; when pouring concrete, the insulation board needs to be used as the mandrel, and the pouring process is cumbersome, which has a certain adverse effect on the reliability of production and the quality of the product
